Abstract

resumo “método e aparelho de melhoria de fala de máscara respiradora” são descritos no presente documento um aparelho de melhoria de fala (20) e máscaras respiradoras (10) que incluem aparelho de melhoria de fala, bem como métodos de melhoria de transmissão de fala para um usuário de uma máscara res-piradora. em uma ou mais modalidades, o aparelho e os métodos de melhoria de fala descritos no presente documento detectam energia acústica dentro de uma primeira faixa de frequências no envelope de ar limpo de uma máscara respiradora e fornecem energia acústica compensadora fora do envelope de ar limpo com o uso de um alto-falante (36). a energia acústica compensadora exibe, em uma ou mais modalidades, um perfil de amplitude atenuada predeterminado de modo que a energia acústica compensadora tenha uma amplitude de menos de 6 db a mais que o perfil de atenuação acústica do corpo da máscara em pelo menos 90% de uma faixa de frequências atenuadas predeterminada.Summary "Respiratory Mask Speech Improvement Method and Apparatus" Disclosed herein is a speech enhancement apparatus (20) and breathing masks (10) including speech enhancement apparatus as well as speech transmission enhancement methods for a user of a breathing mask. In one or more embodiments, the apparatus and speech enhancement methods described herein detect acoustic energy within a first frequency range in the clean air envelope of a breathing mask and provide compensatory acoustic energy outside the clean air envelope. the use of a speaker (36). compensating acoustic energy exhibits, in one or more embodiments, a predetermined attenuated amplitude profile so that compensating acoustic energy has an amplitude of less than 6 db greater than the mask body acoustic attenuation profile by at least 90%. of a predetermined attenuated frequency range.
